Hey im out of conclusions and i need some help with my car. My car has 129k miles on it and i have a weird misfire problem and i need help. I cant figure out the problem i have a misfire on cylinder 6 but i swapped coils and it wasnt the coils or the spark plugs. Its weird cuz when i bought the car the owner told me its been laying out there for a few months.I also did a compression test on each of the cylinders and it came up to 150 on all of them. If anyone came across this problem and knows anything id appreciate the help.

Does the car have any other stored codes?

[MasterKwan]

I'd switch injectors next.

Bad gas? You said its been sitting

[shled]

Codes would be next.

[johnnyts21]

it has few codes like bad idler and the 02 bank sensor and random cylinder misfire. Im going to swap injectors next to see if thats the problem. Ill stay updated

[jaajavon]

change the 02 sensor that probably causing the misfire

Your compression sounds a little low, 190-200 is usually where you want to be.

But the misfire is on cylinder 6 i dont think it has anything to do with the 02 sensor. Im thinking its a bad fuel injector thats causing this misfire. I will replace it today or tomorrow and ill let you guys know
